荞麦籽油脂肪酸的气相色谱/质谱法分析

采用石油醚抽提荞麦籽，然后将油样进行皂化、甲酯化，以毛细管色谱-质谱联用法测定荞麦籽油中的组分，从分离出的50个身中确认了23种组发，所鉴定的组分占总峰面积的96.95％。其中脂肪酸中主要成分含量：C18：2≥32.91％，C18:1≥24.73％，C16：0≥20.04％。奇数碳原子脂肪酸、鲨烯、23s-甲基胆甾醇、5-烯-3β-豆甾醇、5，24-二烯，3-豆甾醇、12-烯-3-醇-齐墩果、12-烯-3-醇-熊果等未见报道。

GC/MS Analysis of Fatty Acid in Fagopyrum Esculentum Seed Oil

In this paper, Fagopyrum esculentum seed oil was extracted with petroleum ether. Hydrolyzed and esterified withpotassium hydroxide and methanol. After saponification and esterification the oil was determined by capillary GC/MS. Morethan 50 peaks were separated and twenty-three compounds representing 96.95% of the oil were identified. C18:2 & C18:1 &C16:0 were chief components, and their relative contents exceeds 32.91% and 24.73% and 20.04%.There are no reported aboutodd number carbon atomy fatty acid, 2, 6, 10, 14, 18, 22-Tetracosahexaene, 23S-Methylcholesterol, Stigmast-5-en-3-ol, Stigmast-5, 24-dien-3-ol, Olean-12-en-3-ol, Urs-12-en-3-ol.
